A scenario creating device creates a scenario file to be supplied to a scenario reproducing device capable of reproducing only image files of a first predetermined format in accordance with a scenario file for pagewise sequential display of images. The scenario creating device includes an input section having a pointing device, a display section, and a scenario creating section. The scenario creating section provides a display of an execution icon on the display section for causing the scenario creating section to execute a scenario creating process. When a single file icon for a single source file of a second predetermined format is dragged and dropped on the execution icon by way of operation of the pointing device, the scenario creating section creates the scenario file on the basis of the scenario information and generates the image files of the first predetermined format on the basis of the image information.
